That still shouldn't get all these distortion issues. I often keep a stereo version of AD2 while trying out ideas. You never answered the questions about samplerate and buffer size. Also it might be interesting to find out if the distortion persists during bounces/exports or only during live playback.

I agree that AD is hot even as a stand alone synth,  I have adjusted the trim levels so that it is almost inaudible. The distortion is still there.  When using AD in Sonar I have all the drums in 1 track. Could this be my problem? I need to map my drums 1rst?

But, where are you adjusting the trim levels - inside AD, or on the Sonar track?  

I want to thank all that responded to my AD post.
I tried all suggested fixes with no success
I uninstalled cakewalk and a fresh install and all is good.
Wish I would have done this 3 days ago. I'm happy now so lookout Platinum here I come...
